Turntable bearing load on the effects of using precision
To maintain a good state of bearing and the use of performance, maintenance, repair, in order to prevent accidents, ensuring the reliability of operation, increase production, economy. To maintain the best operating conditions of the corresponding mechanical operating standards, regular inspections to maintain in good condition and performance Flange slewing bearing of bearings, maintenance, overhaul, in order to prevent accidents, ensuring the reliability of operation, increase production, economy. To maintain the best operating conditions of the corresponding mechanical operation standard, check regularly. Examination content includes monitoring running state, supplement or replacement of the lubricant, periodic disassembly inspection. As a matter of maintenance in operation, a rotary voice, YRT turntable bearing vibration, temperature, the state of grease and so on. Remove bearing overhaul, the first recorded appearance of the bearings, confirm the remaining amount of lubricant, after sampling inspection by the lubricant, cleaning bearings.
On the basis of high precision bearings efficiency for turntable bearing load on the rotation of the ferrule, working condition, the load ring bear is divided into a fixed load, dynamic load and rocking out load three.
A. fixed load synthetic radial load by raceway parts undertaken, and delivered to the shaft or housing appropriate parts of the corresponding range wind appearance. The load bearing in Sweden called fixed bearing load. Unique local fixed load is radial load and the synthesis of relatively static ring. Assume the fixed load. General can choose loose fit.
B. off the dynamic load effect for the synthesis of shaft bearing ring raceway of along the circumferential direction of the rotation, are borne by the various parts of the various parts of the raceway, and accordingly passed to the shaft casing hole appearance. This is called off load dynamic load, also called cyclic loading. Off the unique local dynamic load is relative to the rotating synthetic radial load vector and the ring. Take off the Angular contact ball bearings reproduced bearing ring and shaft or housing holes should choose clearance or interference fit. Synthesis of radial load vectors to the bearing ring raceway in the ring within a given area relative rocking, undertaken for the raceway certain region, and transmitted to the shaft or housing bore the appearance of certain region, or the effect is used for load bearing is the impact load, oscillating load, the the loading direction or digital often changes, the load is called rocking load, also called not the direction of load. Bearing rocking load, especially in the bear the heavy shoulder the burden, inside and outside the circle of which shall be deemed appropriate and use the interference fit. The inner rocking rotation, general inner ring that uses off the dynamic load when appropriate
